    摘要: An apparatus for producing a detachable information sheet includes an image forming device, an applying and curing unit, and a heating and pressing unit. The image forming device includes an image bearing body, an electrostatic latent image forming unit to form an electrostatic latent image on the image bearing body, a development unit to develop the latent image with a toner to form a visible toner image, a transfer unit to transfer the toner image from the image bearing body onto a recording medium, and a fixing unit to fix the toner image on the recording medium. The applying and curing unit applies an energy-ray curable composition precursor onto the recording medium having the toner image fixed thereon, and cures the precursor to form an energy-ray curable composition to coat the recording medium. The heating and pressing unit heats and presses the recording medium coated with the energy-ray curable composition.

    摘要: In an image forming apparatus, a photoconductor and a charge roller are in contact with each other and configured to rotate together at linear velocity v (millimeters/second). In this structure, a DC voltage is applied to the photoconductor and the charge roller while they are not rotating. In this state, parameters such as voltage, linear velocity, pressure contact force between the photoconductor and the charge roller are selected so that the ratio w/v (seconds), where w is the interval between two discharge marks occurring on surface of photoconductor, is between 0.005 to 0.035.
